Answer:
<h3>A. x=5*8</h3>
Step-by-step explanation:
Isolate the term of x from one side of the equation.
![\sf{\dfrac{x}{8}=5 }](https://tex.z-dn.net/?f=%5Csf%7B%5Cdfrac%7Bx%7D%7B8%7D%3D5%20%7D)
<u>First, you have to multiply by 8 from both sides.</u>
![\Longrightarrow: \sf{\dfrac{8x}{8}=5*8 }](https://tex.z-dn.net/?f=%5CLongrightarrow%3A%20%5Csf%7B%5Cdfrac%7B8x%7D%7B8%7D%3D5%2A8%20%7D)
<u />
<u>Solve.</u>
<u />
<u>Multiply the numbers from left to right.</u>
5*8=40
![\Longrightarrow: \boxed{\sf{x=40}}](https://tex.z-dn.net/?f=%5CLongrightarrow%3A%20%5Cboxed%7B%5Csf%7Bx%3D40%7D%7D)
<u>Therefore, the correct answer is "A. x=5*8".</u>
I hope this helps. Let me know if you have any questions.
Answer: vector equation r = (7+3t)i + (4+2t)j + (5 - 5t)k
parametric equations: x = 7 + 3t; y = 4 + 2t; z = 5 - 5t
Step-by-step explanation: The vector equation is a line of the form:
r =
+ t.v
where
is the position vector;
v is the vector;
For point (7,4,5):
= 7i + 4j + 5k
Then, the equation is:
r = 7i + 4j + 5k + t(3i + 2j - k)
<u><em>r = (7 + 3t)</em></u><u><em>i</em></u><u><em> + (4 + 2t)</em></u><u><em>j </em></u><u><em>+ (5 - 5t)</em></u><u><em>k</em></u>
The parametric equations of the line are of the form:
x =
+ at
y =
+ bt
z =
+ ct
So, the parametric equations are:
<em><u>x = 7 + 3t</u></em>
<em><u>y = 4 + 2t</u></em>
<em><u>z = 5 - 5t</u></em>
Answer:
1.42 hours
Step-by-step explanation:
In this case we must take into account that the speed would be to fill a pool for a time, that this case is in hours, therefore it would be like this:
1/5 for the first pipe
1/2 for the second pipe
Now, we will use both at the same time, therefore:
1/5 + 1/2 = 1 / x
0.7 = 1 / x
x = 1 / 0.7
x = 1.42
That is to say that if we use both we will take a total of 1.42 hours
Answer:
A) Container X
Step-by-step explanation:
X=2C:6S ratio, now reduce amount but keep the same ratio
X=1C:3S
Y=4C:8S ratio, now reduce amount but keep the same ratio
Y=1C:2S
Container X has the sweeter water because it's ratio of sugar to water is higher.
